Description

1236392 发明 Description of the invention: [Technical field to which the invention belongs] The present invention relates to a tool for manufacturing a miter nail. The miter nail includes a shaft portion and a head portion, and the head portion is disposed so that its center is offset from the shaft portion. In which, the tool is at least one of at least two sets of tools interacting on a blank for nails, the aforementioned tool includes a front side having a receiving opening and a head when forming a head On the top side used, the receiving opening is shaped to form an imprint in the blank and to secure the blank during formation of a head on the blank. The invention is more related to the use of the aforementioned tools. [Prior Art] A nail system with a skewed head is used in nailing, where a row of nails can be used for multiple launches before a new row of nails is loaded. The rows of nails are line-closely and adjacently assembled, and nails such as thai have heads that are biased / sideways. The deviation is necessary so that there is a large head surface that can be freely exposed (though the nails are tightly combined as described above). These types of nails are known as nails and miter nails. The head has a main method of making nails offset from the head, that is, a metal wire sandwiched between two opposing tools, and the exposed end of the metal wire is tied to the outside of the tool. The exposed end is then flattened with a force = when the partial nail is puppetized, the exposed end is bent before the head is processed. Xi 1236392 However, the shortcomings suffered by this process lock are: a small indeterminate deviation of the head ’and it will extend opposite to the overall deviation. This disadvantage lies in the fact that when nails are quilted, and the nail row female can only assemble a small number of nails at an early length, the user of the nail gun will load new needle rows more frequently. Horse When the nails are tightly assembled, the heads of the nails belong to each other, and the exposed surfaces of 2: 1 are used to launch the nails. The aforementioned surfaces are biased: nails, shafts. This is because when the surface is shot by a nail, the force caused by the impact will deviate correspondingly from the shaft portion. When the nail is launched, the reaction from the nailed object is concentrated on the central axis of the shaft. The distance between the central axis of the part and the deviating force on the nail head produces a significant moment of force on the nail. The nail must be strong enough to withstand the moment of this force. From this point of view, the key part of the nail lies in the transition area between the head of the nail and the shaft. An attempt to overcome the problem of not deviating from small areas has been implemented. This goal has been achieved, but it has created a new problem. By constructing the tool there is an opening just below the head. The small uncut: The wound has been clearly removed. The aforementioned opening has a cross-section in a direction opposite to the deviation, the cross-section is smaller than the relevant cross-section of the metal wire, thereby causing a small deviation of the material The system was displaced and thus removed. Moreover, one of the tools obviously has an upper side which slightly protrudes relative to the other tool to move more material in the deviating direction. Such nails are severely weakened at the critical transition between the head and the shaft. See, for example, the conventional nails shown in Figs. 18a and 18b. When the nails 1236392 are weakened, they have a tendency to cause failure in the nail grab. To solve the problem 'the launch force has been reduced. When the launch force is reduced, the use of the nail grab will be limited. Similar strength problems also occur with nails with heads. Although these heads are not completely deviated, they have reduced non-deviated portions. — [Summary of the Invention] An object of the present invention is to provide a tool for manufacturing an improved nail having an off head, in which the aforementioned disadvantages of the nail are avoided. According to the present invention, the novel and innovative concept of the tool includes: The receiving opening includes a protruding section against the top side to form an embossing on the shaft of the nail, the embossing being placed adjacent to the head And the main adjacent side of the embossing system is opposite to the direction in which the head will deviate; and = the protruding section contains at least one flat or convex surface on the solid f, which is used to form at least one In fact, the flat or concave section on the top, the aforementioned main shaft or the lower and inner sections are placed substantially parallel to the longitudinal opening of the receiving opening: type two: in the transition area between the head of the nail and the shaft Department of flat or convex: ask for strength. The high intensity is achieved by a protruding section of a tool having at least -essentially, the sweeping or protruding: by ... dustprints to produce a smaller than the know-how-= Cheng J and worse the shape of the flat or convex surface. When the embossed shape = the tree opposite to the direction of deviation, the material of the large I is reserved. # 里 η 士 留; ^, Η, moment of inertia Most of the land. It is important to maintain the strength against the moment of force of 1236392 in the transition area with the neck. Nails with full or partial heading can achieve improved strength. The protruding section further bends the blank in the deviation direction, so that a completely deviated head can be obtained, that is, a small portion without the head is deviated and extends slightly in a direction opposite to the deviated direction. And, because of the protruding section, a very stable, solid &#When the tool is used in a continuous manufacturing device, the protruding section also has a positive effect: it can be effectively held before the head is formed. This is important because the free end of the material that will become the head must be bent to obtain a deviating head before the head is formed. Effective gripping will ensure that the ends of the cymbals will be bent without the risk of unwanted displacement of the chain material. The dimensions of the flat or convex surface and the side of the receiving opening against the flat or convex surface are preferably provided in such a way that the cross-sectional area of the needle shaft portion against the flat or concave section will be Substantially corresponds to the adjacent part. + I Magic As a result, it is possible to produce the material on one side when making a print. This will allow the main part of the material to remain at the position of the nail, rather than mainly from the longitudinal axis of the nail. The flat or convex surface and the side of the :: adjacent to the flat or convex surface may be provided with two grooves, which grooves are placed close to the end of the flat: L or convex surface At the parts, the grooves have an extended extension with a radius larger than the radius of the material receiving the opening (the part does not have more than 14 embossing of the nail t). 1236392 The position of the "grooves and the positions of these grooves will cause the material to be produced in a better domain :: The position of" !!!! " Moment. In order to obtain a comparative moment in the required direction 'a large amount of material must remain on the side opposite to the direction deviating from the nail head #. The side of the receiving opening next to the 4 flat or convex surface may contain several areas, the aforementioned area has an extension, the radius of the extension is small = a part of the inner opening (this part does not participate in the dust in the nail印 开 > in) radius. Some materials of y 'on the side of the shaft portion of the nail move in a direction opposite to the deviation direction. This will produce a larger moment of inertia. In one embodiment, the protruding section may include at least one connection section 'the connection section connects at least a portion of at least one flat or convex section with the bottom of the receiving opening', the aforementioned connection section has a recess lower surface. The recessed surface provides a nail with a protruding connection surface that enhances the strength of the nail. In another embodiment, the flat or convex surface may have a minimum height of 0.2 to 2 mm. In another embodiment, the flat or convex surface may have a maximum height of 1 to Ø mm. In another embodiment, the protruding section may have an extension of 0.2 to 2 cm. Any extension will have a variety of effects. However, the best effect is between 0.2 and 2! In the interval between the millimeters. In another embodiment, the protruding section may be provided with a width, and the 10 1236392 width is equal to or smaller than the width of the blank. In a preferred embodiment, the receiving opening may be provided with a depth that is less than the width of the cymbal. A mechanical guardian of this design = and is therefore less expensive. The tool is preferably used on a continuous processing type manufacturing apparatus, but can also be used on other types of nail manufacturing machines. A continuous type manufacturing apparatus in this category is based on, for example, a method for processing a rectangular (ellipsoidal) workpiece and a device for implementing the principles described in the method.
